If you wish to install the NVIDIA Linux graphics driver on a Debian GNU/Linux or Ubuntu system that ships with Xorg 7.x, please ensure that your system meets the following requirements:

* development tools like make and gcc are installed * the linux-headers package matching the installed Linux kernel is installed * the pkg-config and xserver-xorg-dev packages are installed * the nvidia-glx package has been uninstalled with the --purge option and the files /etc/init.d/nvidia-glx and /etc/init.d/nvidia-kernel do not exist

If you use Ubuntu, please also ensure that the linux-restricted-modules or linux-restricted-modules-common packages have been uninstalled. Alternatively, you can edit the /etc/default/linux-restricted-modules or /etc/default/linux-restricted-modules-common configuration file and disable the NVIDIA linux-restricted kernel modules (nvidia, nvidia_legacy) via:

DISABLED_MODULES="nv nvidia_new"

Additionally, delete the following file if it exists:

/lib/linux-restricted-modules/.nvidia_new_installed

Please note: unfortunately, it has become difficult to keep track of the pre-/post-installation steps required for [K]Ubuntu, and the above instructions may be incomplete. If in doubt, it is recommended that you use your distributor's NVIDIA Linux graphics driver packages, exclusively.
